About Phosphate Buffered Saline as a reference compound
Phosphate Buffered Saline is a sterile isotonic phosphate buffer supplied in sealed vials for reconstitution and dilution work. Every PureLabs lot is produced under GMP-aligned synthesis controls, filled and sealed in a controlled environment, then assayed by an independent partner laboratory using reverse-phase HPLC with mass-spectrometric confirmation. Material is released only at or above the stated Sterile diluent threshold; anything below it is rejected rather than sold. The certificate of analysis carries the chromatogram and MS trace for the exact lot you receive and stays archived under reference PL-1434 for the life of the batch. Available in 2 kit configurations, each containing ten vials.
Handling and storage
- Store sealed Phosphate Buffered Saline vials at 15–25 °C, away from direct light.
- Wipe the stopper with an alcohol swab before each withdrawal.
- Use a fresh sterile needle for every withdrawal to keep the vial intact.
- Discard any vial showing particulates, cloudiness or a compromised seal.
Phosphate Buffered Saline — frequently asked questions
Common laboratory questions about sourcing, purity, storage and shipping of Phosphate Buffered Saline.
What sizes of Phosphate Buffered Saline can I order?
Phosphate Buffered Saline ships in 2 configurations: 3 mL/vial · 10 vials/box; 10 mL/vial · 10 vials/box. Prices start at $6 per kit.
What purity is PureLabs Phosphate Buffered Saline?
Current stock assays at Sterile diluent by reverse-phase HPLC with mass-spectrometric confirmation from an independent laboratory. Lots below the threshold never reach the catalog.
Does Phosphate Buffered Saline ship with a certificate of analysis?
Yes. A lot-specific certificate of analysis including the HPLC chromatogram and MS trace accompanies every order and remains retrievable under batch reference PL-1434.
How should Phosphate Buffered Saline be stored?
Keep sealed vials at 15–25 °C away from direct light and discard any vial with visible particulates or a damaged seal.
How quickly does Phosphate Buffered Saline ship?
Orders confirmed before 15:00 UTC dispatch the same working day in insulated, tracked packaging, subject to the import rules of the destination country.
Is Phosphate Buffered Saline sold for human use?
No. PureLabs supplies this material strictly as a reference compound for in-vitro and laboratory research. It is not a medicine and is not for human or veterinary consumption.
